LABEL-QUMMlNG MACHINE.

SPECIFICATION 'forming part of Letters Patent N. 661,101, aerea November e, 1900. Application filed January 18,1900. serial No. 1,874. No more..

To a/ZZ 'zi/hem it 'mayconcerm l Be it knownthat I, HUGO R. GRASSMANN, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Label-Gumming Machines, of which the following is a specilication.

My invention relates to improvements in apparatus for gumming labels; and it consists of a gumming-roller dipping into a body of gum carried by a trough, which is integrally furnished with a strickle or scraper for removing surplus oum from the roller, the said trough being carried by a frame and being capable of a movement therein at right angles to the axis of the roller, so that the strickle can be adjusted to the roller; of feedrollers for feeding the label to be gummed to the gumming-roller; of aguide for directing the label to the feed-rollers; of a takeoff for lifting the gummed label from the gumming-roll; of means. for` holding the label in contact with the gumming-roll and preventing it from being carried around the feedrolls, and of certain details of lconstruction, as hereinafter fully described. f

In the accompanying drawings, forming part of this specification, and in which similar characters of reference indicate similar parts throughout the several views, Figure 1 is a plan of my label-gumming machine; Fig. 2, a side elevation of Fig. l; Fig. 3, a section of Fig. l on line A B; Fig. 4, a plan of one end of gumming-roll and part of gum-carrying trough, showing strickles for wiping face and end of roll.

a is a frame; b, a trough or box carried in frame et and furnished with a strickle or scraper c.

d is a spring carried by frame c, bearing a against the forward end of boXgor trough b;

c, set-screws carried by rear part of frame a and bearing against the rear end of trough label.

p is an operating-crank on gumming-roll f; q, a gear on this roll gearing into and driving a gear r Onfeed-rollj; s, a gear on feed-roll Je, gearing into and driven by gear fr; t, a

pawl engaging gear q and preventing a backward movement of the several'rolls.

Lt is a take-off engaging the roll fand insuring the label leaving this roll after being gummed.v The ends of this take-olf are carried detachably in bearings in top .h and held in position by springs w.

:c is a bar carried by top h or by brackets y, carried on the shaft of rollj, which keeps label in contact with gumming-roll and prevents it after it has passed between the rolls from being carried up around rollj.

lis a feeding-table for carrying the label to the feed-rolls j k. The lower'end of this table is furnished with projecting fingers 2, which enter grooves 3 in the face of roll lc and which positively guide the label in between the feed-rolls j le.

In operating the device the label is placed on the feeding table and the crank p is turned, driving the several rolls, the feedrollsj le carrying it down to the gumming-roll, and it passes over the top of this roll and is lifted therefrom by the take-olf.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In agumming-machine, in combination', a frame, a trough carried by said frame and .adjustable transversely thereof, a strickle carried by said trough, a gum ming-roller carried longitudinally of said frame, a top hinged to .said frame, feed-rollers carried by'said top, means whereby said gumming and feedrollers may be driven, a feeding-table for carrying labels to said feed-rolls, and a take-o@ forlifting the gummed label from said gumming-roll.

2. In a gumming-machine, in combination, a frame, a gum-carrying trough carried by said frame, a strickle formed integrally with IOO Y m said trough, a gumining-roller carried by said which is furnished with a series of grooves,

frame, a spring carried by said frame engaging the side of said trough opposite to the operative end of said strickle, and set-screws carried by the side of said frame opposite to said spring, said screws and spring operating jointly to adjust the bearing of said strickle against the gum ming-roller.

3. In a label-gumming machine, in combination, a gum-carrying trough, a guininingroller passing through said trough, a pair of feed -rollers, the face of the under one of a feeding-table fn rnished with a series of lingers adapted to enter said grooves, a take-Gif engaging said gumming-roll, means for revolving said gumming and feed rolls, and a bar for keeping label in Contact with guur ming-roll and preventing the label from passing up around the upper feed-roller.
